That's not to say he can't come back and have a brilliant career, but this is a definite setback.
I heard of that Champman guy a couple weeks ago, haven't checked him out yet.
Curveballs and sliders actually put more strain on the UCL than a fastball does, but when you mix in the offspeed pitches with a 100mph fastball all while having poor mechanics, its no wonder this didn't happen sooner
